Why is electricity invisible?

Answer 1

Electricity is free electrons in motion. Since electrons have no mass they cannot reflect visible light and therefor can't be seen. The effects of electricity can be seen. Lightning bolts are visible because the electrons traveling through air excite the gas molecules to higher, unstable energy states and they return that energy in the form of light and heat.

Answer 2

Electricity is invisible because of the fact that the particles that make it up are much too small to see. Electricity it the movement of electrons and electrons are the smallest known part of an atom. The lightning or sparks you see are because of the air being heated up to the point that it glows for a very brief second.

Answer 3

Electricity is only invisible when we limit our perspective to the human eye.We don't have the technology to view the billions of electrons flowing though a copper wire when you hit your light switch.
We do however know that when the flow hits a resister,such as a light-bulb fillament,the resistance and friction makes heat.Heat burns things,fire makes light.

Answer 4

visibility is based on the radiation on electromagnetic energy, or waves, in the range of 380 to 780 nm. Electricity that flows through wires and other conductors does not produce EM energy in this wavelength band. You can see electricity in the form of static sparks and lightning. These forms of electricity release energy to the surrounding air that displayed in either blue, 450–495 nm, or white, which is the entire spectrum.

Answer 5

Actually electricity is nothing but it is the flow of electrons which has very less dimensions i,e, not seen by naked eyes that is why electricity is invisible

Answer 6

Nope. firstly electrical energy IS seen. Ever see lightening, sparks in a cat's fur, or a spark once you plug some thing into the wall? that's electrical energy! additionally electrical energy is measurable and behaves in predicable techniques while presented to rely. No god has those characteristics.

Answer 7

How would it be a shock, if you could see it coming ?

But seriously, sparks and lightning are not electricity, they are both visible effects of electrical discharge on either air molecules, or other materials, tiny smidgens of metal or whatever, that's why spark plugs need to be re-gapped, and eventually replaced.

To be semantically correct though, electrons are visible, just not in the tiny band of the electromagnetic spectrum in which our visual receptors usually function.

Next Thunder Storm look up..
Not all electricity is invisible.

Answer 9

If electricity's invisible, how can you read your computer display?

You can also see electrons directly, with a vacuum tube containing a heated electrode. The electrons make an eerie blue glow.

Answer 10

Because it would take all the fun out of it if you could see it. My husband (who's well insured!) was piggling paint out of a wall socket with the pointed end of a screw driver. Do you think he'd be that insane if there was a bright, dangerously blue light glaring at him from the little holes? I think not!
